    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    Money Multiplier and Business Cycle in the United States

    No full text
    The monetary policy has the power to influence the real economy. Whether it is conducted through discretion or a stable policy rule, it requires some adjustments of the money supply directly connected to the money multiplier. This thesis investigates the relationship between money multiplier and real output in the United States in terms of the direction of causality in order to test the predictions of competing business cycle theories. While monetarism predicts the causality running from money multiplier to real output, both post-Keynesianism and real business cycle theory predict the reverse relationship. The main results of this thesis confirm the monetarist theory for both the period before the financial crisis and the entire time period since 1960. The validity of monetarist prediction, however, depends on the empirical definition of the money supply. While in the shorter of the examined periods, the monetarist prediction holds for the M2 money multiplier, in the longer period, it holds for the money multiplier of M1.Menová politika má silu ovplyvňovať reálnu ekonomiku. Či už je vykonávaná prostredníctvom diskrečnej politiky, alebo stabilného pravidla, vyžaduje určité zmeny peňažnej zásoby, ktorá je priamo prepojená s peňažným multiplikátorom. Táto práca skúma vzťah medzi peňažným multiplikátorom a reálnym výstupom v Spojených Štátoch, z hľadiska smeru kauzality, s cieľom otestovať predikcie súperiacich teórií hospodárskeho cyklu. Zatiaľ čo monetarizmus predikuje kauzalitu smerujúcu od peňažného multiplikátoru k reálnemu výstupu, post-Keynesizmus a teória reálneho hospodárskeho cyklu predikujú opačný vzťah. Hlavné výsledky tejto práce potvrdzujú monetaristickú teóriu pre obdobie pred finančnou krízou aj pre celé obdobie od roku 1960. Platnosť Monetaristickej predikcie však závisí na empirickej definícii peňažnej zásoby. Zatiaľčo v kratšom zo skúmaných období, monetaristická predikcia platí pre peňažný multiplikátor M2, v dlhšom období platí pre peňažný multiplikátor M1

    Unconventional Monetary Policy Rules in a TANK Model

    Diplomová práca skúma vplyv nekonvenčných pravidiel menovej politiky založených na rozsiahlych nákupoch a predajoch finančných aktív na blahobyt ekonomických subjektov a porovnáva ich s konvenčnými pravidlami, a to tak pri záväznej nulovej dolnej hranici, ako aj mimo nej, pomocou prístupu založenom na evaluácii stratových funkcií. Na tento účel je stredne veľký novokeynesiánsky DSGE model s reprezentatívnymi agentmi, ktorý zahŕňa viaceré rozšírenia, ako finančné frikcie a zvyky v spotrebe, rozšírený o dva typy agentov čeliacich rôznym úverovým obmedzeniam, držiacich reálne peňažné zostatky, ktoré im prinášajú úžitok. Rozšírený model vykazuje štandardnú dynamiku TANK modelov, ktorá je použitá na evaluáciu stratových funkcií. Výsledky naznačujú, že využívanie nekonvenčných pravidiel menovej politiky v kombinácii s konvenčnými môže zlepšiť stabilizačné schopnosti centrálnych bánk, bez ohľadu na to, či je nulová dolná hranica záväzná alebo nie.The thesis examines the impact of unconventional monetary policy rules based on large purchases and sales of financial assets on the welfare of economic agents, comparing them to their conventional counterparts, both at and outside the zero lower bound, using the loss function evaluation approach. For this purpose, a representative-agent medium-scale New Keynesian DSGE model, encompassing multiple extensions, such as financial frictions and habit formation, is expanded to include two types of agents facing various borrowing constraints, who hold real money balances from which they derive utility. The expanded model exhibits standard TANK dynamics, which is used to evaluate the loss functions. The results suggest that the use of unconventional monetary policy rules in conjunction with conventional ones can enhance the stabilization capabilities of central banks, regardless of whether the zero lower bound is binding or not
